Re: Furnace starts, then shuts off.
It wouldn't hurt to clean the flame sensor, you may want to take a look at the over-temp limit switch (assuming this furnace has one) it is probably located above the burner area, on the housing that the blower blows air across before it is circulated into the house. Incidentally is your flame color orange or blue? It should be blue.
